摘要
将现代的斜拉桥和古典的拱桥有机结合组成一种新型的桥式结构,充分发挥了斜拉桥与拱桥的优点,造型新颖美观,别具一格。湘潭市湘江四大桥主桥采用120 m+400 m+120 m斜拉钢管混凝土飞燕式拱桥,论述这种新颖桥型结构体系创新技术的构思与基本受力性能,研究结果表明,该新型组合桥式结构桥梁,具有索拱共同受力、相互作用等特性,提高了结构的跨越能力、刚度和稳定性。
The organic combination of modern cable-stayed bridge with classic arch bridge to form a type of new bridge structure will bring into full play the respective advantages of both the cable-stayed and arch bridges. The configuration of the new bridge structure will be aesthetic and will have its unique style. For the 4th Xiangjiang River Bridge in Xiangtan City, the main bridge is designed as a cable-stayed arch bridge of concrete-filled steel tubes with span arrangement 120 m＋400 m＋ 120 m. In this paper, the considerations for the innovative techniques and fundamental mechanical properties of the structural system of the type of the new bridge are presented. The results of study indicate that the cables and arches of the bridge can work in a joint way, interact each other and consequently can improve the spanning capacity, rigidity and stability of the bridge structure.
